Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov raj tooj liab yog lawv cov kev tiv thaiv corrosion. Tsis zoo li lwm cov ntaub ntawv, xws li hlau lossis hlau, cov raj tooj liab tsis xeb yooj yim thiab tiv taus corrosion nyob rau hauv ib puag ncig hnyav. Qhov no txhais tau hais tias cov kav dej tooj liab tuaj yeem siv sijhawm ntev yam tsis tas yuav hloov pauv, txuag lub tsev thiab cov tswv lag luam sijhawm thiab nyiaj txiag.
Tsis tas li ntawd, cov raj tooj liab muaj qhov ua tau zoo rau qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev siv hauv cov kav dej uas thauj cov kua los yog roj ntawm qhov kub siab lossis kub. Cov raj tooj liab kuj tseem muaj cov thermal conductivity zoo heev, txhais tau tias lawv tuaj yeem thauj cov dej kub thiab cov pa roj tau zoo.
Lwm qhov zoo ntawm cov kav dej tooj liab yog lawv qhov yooj yim thiab yooj yim ntawm kev teeb tsa. Cov raj tooj liab tuaj yeem txiav tau yooj yim thiab khoov kom haum rau txhua qhov kev tsim yeeb nkab, txhais tau tias lawv muaj ntau yam thiab tuaj yeem siv rau ntau yam kev siv. Tsis tas li ntawd, cov raj tooj liab yog ib qho yooj yim rau solder thiab koom nrog lwm cov ntaub ntawv, ua rau lawv yooj yim rau nruab rau hauv txhua qhov kev tsim kho.
Hais txog lawv cov kev cuam tshuam ib puag ncig, cov raj tooj liab yog cov khoom siv rov ua dua tshiab thiab tuaj yeem rov siv dua yam tsis tau poob lawv lub cev. Qhov no txhais tau hais tias kev siv cov raj tooj liab hauv cov kav dej yog qhov kev xaiv ruaj khov thiab kev nyab xeeb, vim tias lawv pab txo qis cov khoom pov tseg hauv qhov chaw pov tseg.
